Solution Overview
Problem
Conventional arc melting furnaces require labor-intensive and cumbersome external operation to turn over alloy ingots, leading to increased working hours and reduced workability due to the need for manual handling and repeated cooling, turning, and melting processes.
Innovation Solution
An arc melting furnace apparatus with a rotating turning member and a resilient turn-over assisting member within the melting chamber that automatically lifts and turns over alloy ingots, reducing the need for external manipulation and minimizing the risk of ingot loss or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a turning bar is operated from outside the melting chamber to turn over alloy ingots, then the alloy can be turned over for repeated melting and kneading, but the operation becomes labor-intensive and time-consuming
Solution Approach 1:
The turning member is equipped with a self-service mechanism where the alloy ingot itself becomes the actuating force. When the ingot is placed on the turning member, its weight automatically causes the turning member to rotate, turning the ingot over without requiring external manual operation. This eliminates the need for workers to manually hook and turn the ingot, significantly reducing operational burden while maintaining processing efficiency
Solution Approach 2:
The turning member is designed to be rotatable and dynamically responsive to the presence of the alloy ingot. The system transitions from a static external operation to a dynamic self-actuating mechanism where the ingot's placement automatically triggers the turning action through gravitational force, making the system adaptive and responsive without external control
2Stability of the object's composition
If manual turning operations are performed repeatedly, then alloy homogeneity can be improved, but working hours increase significantly
Solution Approach 1:
The turning member enables periodic automatic turning of the alloy ingot at regular intervals during the melting process. The self-actuating mechanism allows the ingot to be turned over repeatedly without manual intervention, maintaining the periodic action needed for alloy homogeneity while eliminating the time loss associated with manual operations. The system can be configured to turn the ingot multiple times automatically
Solution Approach 2:
The automatic turning mechanism ensures continuous useful action by eliminating idle time between turning operations. While manual turning requires workers to repeatedly enter and exit the chamber, the automated system maintains continuous processing, with the alloy being turned over automatically without interruption to the melting cycle, thereby improving alloy homogeneity without increasing working hours
3Productivity
If external manipulation is used to turn over ingots, then the alloy can be processed, but the risk of ingot loss or damage increases
Solution Approach 1:
The turning member acts as an intermediary between the alloy ingot and the melting chamber environment. Instead of direct manual manipulation that risks dropping or damaging the ingot, the turning member provides a controlled interface that safely rotates the ingot. The ingot remains on the turning member throughout the process, eliminating the risk of loss or damage associated with external manual handling
Solution Approach 2:
The self-service turning mechanism eliminates the need for external manipulation entirely. The alloy ingot automatically turns itself over on the turning member through its own weight, removing human hands and external tools from the equation. This self-contained process ensures the ingot remains secure throughout the turning operation, significantly improving reliability and preventing ingot loss or damage

Function Achieved in This Case
The solution significantly reduces the operational burden on workers by automating the turning process, shortening working hours, and preventing ingot loss by ensuring continuous operation and efficient alloy processing.
Implementation Method 1
arc electric discharge is generated between the tungsten electrode (cathode) of the water-cooled electrode 203 and the metal material on the copper mold 201 (anode), so that a plurality of different metal materials are melted with heat energy of the discharge
Implementation Method 2
the molten bottom which is in contact with the mold is cooled, since the metal materials are melted on the water-cooled mold

AI summary
An arc melting furnace apparatus is provided which reduces an operation burden on a worker and shortens working hours. An arc melting furnace apparatus 1 includes a housing 2 having formed therein a melting chamber 2a, a hearth 4 provided within the melting chamber 2a and having a recessed portion 4a, and a heating mechanism 10 for heating and melting a metal material supplied into the recessed portion 4 to generate an alloy ingot. The apparatus comprises a turning member 23 rotatably supported on a supporting member 21 standing within the melting chamber 2a, a perimeter edge of the turning member 23 rotating and moving along the inner surface of the recessed portion 4a to lift the alloy ingot generated in the recessed portion 4a above the hearth 4 and turn it over, and a resilient turn-over assisting member 24 provided above an upper end of the recessed portion 4a. Further, the turn-over assisting member 24 is arranged to flex by a predetermined amount when the alloy ingot abuts it, and to return to its original state from the flexed state so that the alloy ingot is urged to drop into the recessed portion 4a.
